The Vietnamese word "sởn" is a verb that means "to creep" or "to stand on end." It is often used to describe the sensation of feeling goosebumps or a shiver running down your spine, usually because of fear, excitement, or a strong emotional reaction.
While "sởn" primarily relates to physical sensations of creeping or standing on end, it can also imply a feeling of thrill or excitement in certain contexts, especially in literature or storytelling.
